To all whom t may concern.'

Be it known that I, JULES PASCHE- ,HUGUENIM a citizen of Switzerland, residing atk Lausanne, canton of Vaud, inthe Confederation of Switzerland, have invented certain new and useful Improvements in Silencing Joints for Domestic Water Gon- 1 duits, of which the vfollowing is a specification. x

The object of'my invention is a joint for use in domestic water conduits or pipes that does away' with the propagation of; sounds tight manner and at the-same time avoids the gargl'ing sound resulting in the pipes when air bubbles are carried along by the 3 iiowin g water.

The drawing shows by way of example a working form of the invention.

a. and c are the ends of two pipes which are to be connected together bya silencing joint according to the invention.

For this purpose an intermediate tube or pipe b is fixed at the extremity of pipe a by means of an interiorly threaded sleeve d. The intermediate pipe b is entered into a rubber joint or sleeve e which is connected in such a manner to the inner shoulder f1 of the junction box f that it acts as a kind of a dashpot for the longitudinal and the lateral or radial vibrations which may be caused for instance by a shock from outside or by a water-hammer in the piping. The rubber joint e is maintained in its place and pressed against the shoulder f1 by a threaded member g and ring h constituting a stuii'- ing box.

Into the pipe b is itted a rubber hose i containing a screw 7c provided with entrance aperture k1. This arrangement forces the water arriving by pipe a to pass through the entrance aperture k1 and to iow in the path between the threads of screw la which is tightly pressed against the wall of rubber hose i but without penetrating into the rubber. The flow of the water thus regulated and -directed takes place without causing any noise which often is produced in ordinary joints by the air bubbles which have accumulated along an expansion of such junctions.

Of course the invention may be contained in many forms of the silencing joint, all of which come within the purview of my claims hereafter described. vFor instance instead of using any intermediate tube one might fit the inner and the louter elastic sleeve right' in and onto one of the ends ofone `of the pipes which are to be joined, and linstead of a screw, as shown in the drawing the flow of water' might be directed andy guided by some other member inserted` into the Vinner elastic sleeve. i

Havingnow described my invention and the'manner'in which it may be performed, what I claim is:

l. In a silencing joint for domestic water conduits adapted to prevent the propagation of sounds arising in said conduits, a Vhose or sleeve of elastic material' adapted to be inserted into one end of oner of the pipes to "beconnected, said sleeve containing a contracted passage for the flow loi the water,

" an elastic outer `sleeve adapted to be mount-v ed upon said end,'a junction box adapted to be ,screwed onto an end of the other pipe to be connected, and ymeans to presssaid elastic outervv sleeve both lclosely upon the circumference of the first mentioned pipe kand against the inner wall of the junction box, substantially as described.

2. In a silencing joint for domestic water conduits adapted to prevent the propagation of soun-ds arising in said conduits, an intermediate connecting tube, a hose or sleeve of elastic material inserted into said connecting tube, said sleeve containing a contracted passage for the iow of the water, an elastic outer sleeve mounted upon said intermediate tube, a junction box adapted to be screwed onto an end of one of the pipes to be connected, and means to press said elastic outer sleeve both closely upon the circumference of said tube and against the inner wall of the junction box, an interiorly threaded sleeve for connecting the intermediate tube a-fter its being itted with the inner and outer sleeve of elastic material to l an end of the other pipe to be connected, substantially as described.

3. In a silencing joint for domestic water conduits adapted to prevent the propagation of sounds arising in said conduits, a hose or sleeve of elastic material adapted to be inserted into an en-d of one of the pipes to be connected, said sleeve containing a contracted passage for the How of the water, an elastic outer sleeve adapted to be mounted upon said end, a junction box adapted to be screwed onto an end of the other pipe to be connected, shoulders in the inner wall of llO said junction box, and means to press said elastic outer sleeve tightly upon the circumference of the iirst mentioned ipe and also against the inner Wall of the junction box, and particularly onto the shoulders provided in it, substantially as described.

4. In a silencing joint for domestic Water conduits adapted to prevent the propagation of sounds arising in said conduits, a hose or sleeve of elastic material adapted to be inserted into an end ci one of the pipes to be connected, a member inserted into said sleeve, to form a tortuous passage for the fiow of the liquid, an elastic outer sleeve adapted to be mounted upon said end, a junction box adapted to be screwed onto an end of the other pipe to be connected, and a stuling box to secure said outer sleeve in assembled relation, substantially as described. v

5, In a silencing joint for domestic Water conduits adapted to prevent the propagation of sounds arising in said conduits, an intermediate connecting tube, a hose or sleeve of elastic material inserted into said connecting tube, said sleeve containing a contracted passage for the flow of the Water, an elastic outer sleeve mounted upon said intermediate tube, an interiorly threaded sleeve for connecting the intermediate tube after its being fitted with the inner and outer sleeves of elastic material to an end of one of the pipes to be connected, a junction box adapted to be screwed onto an end of the other pipe to be connected, shoulders in the inner walls of said junction box and means to press said outer sleeve tightly upon the circumference of the tube and also a ainst the inner Wall of the junction box, an particularly onto the shoulders provided in it, substantially as described.

6. In a silencing joint for domestic Water conduits adapted to prevent the propagation of sounds arising in said conduits, an intermediate connecting tube, a hose or sleeve of elastic material inserted into said connecting tube, al member inserted into said sleeve, to form a tortuous passage for the iioW of the liquid, an elastic outer sleeve mounted upon said intermediate tube, an interiorly threaded sleeve for connect-ing the intermediate tube after its being fitted with the inner and outer sleeve of elastic material to an end of one of the pipes to be connected, ,a junction box engaging said outer sleeve adapted to be screwed on an end of the other pipe to be connected, and a stufi'ing box to secure said outer sleeve is assembled relation, substantially as described.

In testimony whereof I aix my signature in presence of tvvo Witnesses.
